Currently, if you start a long-running evaluation (maybe even an infinite loop) and want to kill it, you have to kill the server, start a fresh one, and reopen/reload everything to continue working.
It would be great to have a way to kill the evaluation and continue working without all of those steps.
If it is necessary to kill and restart the server, then it would be nice if that could be done automatically. But it'd be better if the killing and restarting could be avoided altogether.
